This milestone has made the popular messaging service the second platform to have reached that number of users. The Facebook-owned app said it has amassed two billion users, up from 1.5 billion it revealed two years ago.
"WhatsApp started with the goal of creating a service that is simple, reliable, and private for people to use".
".no one in between can read your messages or listen to your calls, not even us".
Along with making this huge announcement, WhatsApp has also spoken about how it will continue to keep conversations made across the service private.
WhatsApp has introduced features for businesses
WhatsApp CEO Will Cathart told The Wall Street Journal that the company will not change its encryption policy, even it means flouting directions of the regulatory bodies of select countries demanding decryption of chat messages.
The platform also promised to work with top security experts, employ industry leading technology to "stop misuse as well as provide controls and ways to report issues - without sacrificing privacy".
The two-million milestone is a big feat for WhatsApp, which organically gained vast popularity in developing markets such as India where calls and texts were fairly expensive for most people.
It's no secret that WhatsApp is now the most popular chat app on the planet but it seems this service is getting bigger by the day.
The heads of Facebook's WhatsApp and Messenger, Will Cathcart and Stan Chudnovsky, responded in a letter to officials from the three countries that allowing this kind of "backdoor" access "would be a gift to criminals, hackers and repressive regimes" while leaving users vulnerable. Coworkers can collaborate, and businesses can grow by easily connecting with their customers.
